Tailgate Detector - TD
The Essential Security
Layer for Your Access
Control Systems
How TD
Today’s access control systems are
designed to help control and manage authorized access to secure
areas. Ensuring that every individual
has properly presented a valid ID or
successfully cleared biometric identification is a major challenge faced
by security professionals. Preventing
tailgating and piggybacking, in other
words misleading or outsmarting the
system, is a problem existing solutions
do not sufficiently address.
IEE has developed a 3D sensor that
uses MLI (Modulated Light Intensity)
technology. This technology is based
on the optical time of flight (TOF) principle, where an active, non-scanning
light source emits modulated nearinfra-red light. The phase shift between
the light emitted by the source and
the light reflected by the people and
objects in the field of view is measured to create a real-time topographic
image of the monitored area. The 3D
MLI Sensor™ calculates the exact number of people transiting the detection
area and triggers an alarm when it
detects situations such as tailgating or
piggybacking.
IEE’s Tailgate Detector TDflex™ 1 offers
a solution that ensures only authorized
people can enter a restricted area by
adding an additional and essential
security layer.
Works
Efficient Security Staff Support
With IEE’s TDflex™, businesses can
optimize the scheduling of their security staff. As the sensor is fully automated, security staff do not need to physically monitor access points – they will
be alerted if there is a security breach
– and TDflex™ reduces the potential
for human error.

Features
High Accuracy
Sophisticated algorithms and extensive test scenarios ensure reliable
detection of people and objects in the
detection area. These test scenarios,
which consist of people carrying or
wheeling luggage, wearing hats, or
walking closely together, show that
TDflex™ can both handle people
carrying objects and detect multiple
individuals in close proximity.
Reliability in Changing Light Conditions
As the sensor emits its own illumination, the performance is not influenced
by artificial light and the sensor also
works in the dark.
Embedded Software
Due to its integrated firmware, the
sensor does not require any additional
computer or server to process the data
it captures.
Sensor Management Tool
The computer-based, multi-lingual sensor
management tool enables management of multiple sensors and offers the
following features:
•• Multi-sensor
configuration
and
backup
•• Fast software updates via the Ethernet network
•• The ability to copy any given configuration to multiple sensors
•• Multi-sensor status monitoring and
advanced diagnostics
•• Password-protected configuration
•• Language selection
Semi-Automatic Calibration
After configuring basic parameters
such as mounting height, detection
width and length, the sensor calibrates
itself within a few seconds. During
this calibration, the sensor checks the
empty detection area and captures the
presence of fixed objects and walls.
Digital I/O Module
TDflex™ comes with a separate I/O
module that features seven digital
inputs and eight digital outputs. This
module, which is powered via TDflex™,
should be installed on the secure side,
in order to maximize security.
Audible Feedback for Confirmation
and Alerts
TDflex™ has an integrated buzzer
which can be used to give individual
acoustic feedback for such things as:
•• Pre-alert
•• Tailgate alert
•• Access allowed/impeded
•• More than one have entered (real
mantrap mode)
Self-Diagnostics
A self-diagnostic routine runs at startup and is regularly repeated to detect
any sensor malfunction.
Data Logging
Historical data and system events:
•• Tailgate alerts
•• Abort credits
•• Bypass on/off
•• Superuser requests
•• System errors
Superuser Mode
This is a temporary directional bypass,
triggered by a person using a specific
superuser badge with an access control device, that allows the superuser
to:
•• escort visitors without credentials
•• enter with carts containing very
large objects of any shape

Features
People Counting
Easy Installation
In addition to its access control features, TDflex™ can also be used as a
People Counter:
The TDflex™ Design Housing - available in white, black and gray - provides
easy and aesthet-ic integration into
existing building architecture. The
Design Housing can be integrated
into dropped ceilings (“Flush mount”),
on the ceiling (“On-ceiling”) or, by
using an extension, below the ceiling
(“Under-ceiling”) offering increased flexibility for all kinds of ceiling structures.
TDflex™ is compatible with single or
double doors swinging into the field of
view and can be installed either on the
unsecure side (preferred) or the secure
side.
•• Forward/Backwards counts
•• Current number of people in the
detection area
•• Zone occupancy. Triggering of an
alert (SMS, e-mail, relay), if occupancy exceeds or falls below the set
thresholds
•• If there are multiple access points,
the occupancy of the entire area can
be monitored in the IEE Occupancy
Tool (XML-RPC option required)
•• Historic counting data logging,
analysis and reporting
Advanced Anti-Tamper Protection
With its optical, mechanical and electronic functionalities, TDflex™ now
offers improved anti-tamper protection. This greatly reduces the chance
that anyone can manipulate the sensor.
Seamless Integration into Existing
Access Control Systems (ACS)
TDflex™ interfaces with any ACS via
digital inputs and outputs (I/Os). These
signals allow you to control the doors
and trigger alerts if there has been a
security breach.
If a person who has authenticated
decides not to enter the secure area,
TDflex™ sends an “abort credit” signal
to the ACS.
In addition to the digital I/Os, the
ACS can also communicate directly
with TDflex™ via XML-RPC (optional).

Operating Modes
TDflex™ is a Tailgate Detector with two
main operating modes:
•• Virtual mantrap
•• Real mantrap
Virtual Mantrap Mode
Real Mantrap Mode
In this mode, TDflex™ monitors single access points to
and from a secure area and
is usually installed in front
of doors. It is also possible
to monitor mechanical or
optical turnstiles, or virtual
access points without any
physical barrier.
If an unauthorized person
Unauthorized
attempts to gain access,
access at turnstiles
TDflex™ generates an
alert. This means that, depending on
the security strategy, the door can
be locked as a preventative measure
(“high security strategy”), or if the
secure area is breached, an alert can
be triggered.
TDflex™ can also monitor people leaving the secure area to ensure there is
no tailgating – effectively forcing people to badge out.
In the real mantrap
mode, TDflex™ monitors any space within
two or more interlocking doors. In this mode,
TDflex™ does not consider
aut hent icat ion
credits (inputs) from the
access control system;
it continuously provides
Mantrap
the occupancy status of
the mantrap. This is then used to safely
control the doors.
In the virtual mantrap mode the following outputs are provided:
•• Access recommendation
•• Pre-alert
•• Tailgate alert
•• Status indicators
•• Abort credit
With the classic strategy of “single person transfer”, which enforces the transit of one person at the time, TDflex™
provides the following outputs:
•• Empty
•• Only one person
•• Suspicious e.g. more than one person or a person behaving abnormally
As an alternative to “single person
transfer”, TDflex™ can also ensure
secure transit of multiple people at a
time, by counting the people inside
the mantrap. This allows for higher
throughput without compromising
security.
